Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds value by previewing the response shape ('which countries block it and the overall global risk level'), but says nothing about scoring methodology, freshness, or platform-name validation against the enum-less string parameter.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two tight sentences with no filler, and the scope constraint is front-loaded before the return-value summary. It is efficient, though the second sentence is essentially a terse result preview rather than essential call guidance.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read-only, single-parameter lookup with no output schema, the description tells the agent what to pass and what comes back (blocking countries plus a global risk level). Only minor gaps remain, such as whether unknown platforms error or return an empty result.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and the single 'platform' parameter is fully documented with eight concrete example values, so the schema carries the semantic load. The description adds no format, casing, or normalization guidance beyond what the schema provides, matching the baseline 3 for high-coverage single-parameter tools.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Get censorship risk score for a specific platform') plus the scope ('across all monitored countries'), which distinguishes it from country-centric siblings like get_country_profile. It does not explicitly differentiate itself from the closely named get_platform_scores, so it falls short of a 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is only implied by the scope phrase 'across all monitored countries'. There is no explicit statement of when to pick this over the very similar sibling get_platform_scores, nor any exclusions or prerequisites, leaving the agent to infer routing.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
